- An Azure Sphere-based device with development features (see Get started with Azure Sphere for more information).
- Setup a development environment for Azure Sphere (see Quickstarts to set up your Azure Sphere device for more information).
Note that the Azure Sphere High Level application is configured for the 21.04 SDK release.
The project supports the Seeed RDB with an Adafruit VS1053 board.
Here's the pinout used in the project the Seeed RDB pinout diagram is here)

| VCC | Header 3, Pin 3 | NA |
| GND | Header 3, Pin 2 | NA |
| DREQ | Header 2, Pin 6 | VS1053_DREQ |

The VS1053 project code exposes four functions:
- VS1053_Init to initialize the hardware
- VS1053_Cleanup to cleanup SPI and GPIO resources
- VS1053_SetVolume to set the volume level (0 is off, 30 is max)
- VS1053_PlayByte to play audio data
The project is configured to play an embedded resource audio file, and also supports internet radio streaming. To enable the internet radio stream uncomment the add_compile_definitions line in the following block in the CMakeLists.txt file.
